Abstract: Изобретение относится к способу получения привитых сополимеров из материалов на основе пропиленового полимера. Способ включает облучение материала на основе пропиленового полимера в отсутствие кислорода, добавление к облученному материалу полимера регулируемого количества кислорода в диапазоне от 0,004% до 15% (об.) при 40°С-140°С для получения материала на основе окисленного пропиленового полимера, содержащего более 1 ммоль совокупного пероксида на один килограмм материала на основе пропиленового полимера. После чего материал на основе окисленного пропиленового полимера, необязательно, нагревают в неокисляющей атмосфере и обрабатывают в неокисляющей атмосфере с использованием, по меньшей мере, одного прививаемого мономера, способного полимеризоваться по свободно-радикальному механизму, в присутствии, по меньшей мере, одной добавки, регулирующей молекулярную массу боковых цепей полимеризуемого прививаемого мономера, с последующей деактивацией остаточных свободных радикалов в получаемом в материале и удалением из материала непрореагировавшего винильного мономера.
